I was talking on the phone when the UFO materialised hovering in the garden of my homes. I was about ten years old. It looked very much like a UFO cartoon with two deep plates put together and a small plate on top. There was round windows all the way around a the center of the two plates and around the small plate on top. It never appeared really solid, and when I began thinking to get a camera it vanished, it had no color. I would say diameter was approx 8meters and 4meters high. The construction appeared to be to small to fit humans. At least that was my thought at that time.
